But, there's an easier and cheaper way to accomplish this. Many bike riders who own SUVs make their own racks. You can buy two or three front-fork mountssuch as Yakima's Blockhead fork mount ($20; www.yakima.com) or Performance's XPORT Universal Bike Mount ($20, though often on sale for $10; www.performancebike.com). Then cut a length of two-by-six wood to fit across your SUV's cargo floor. Screw the fork mounts to the lumber, and you're all set. The bikes will sit nice and stable with that setup.
I used something similar in my Mitsubishi Montero for years, and now have a homemade three-bike stand that goes in the back of the old Ford F250 I use to rattle up to mountain-biking trails near here. Your total outlay will probably be around $60.
